What date is most important?

Savannah • Baby girl - Aliviah Mae 10.29.15 & Baby boy- Archer Neil 05.31.17 👨‍👩‍👧‍👦
I need you ladies to help me pretty please! My husband and I are getting tattoos commemorating our relationship after 5 years together (I know, I know please no hate. I don't need a lecture on why you shouldn't put a significant others name on your body). Anyways, I am thinking about getting our initials and the date of us dating but would our marriage date be more important? Also do you think I should use my initials with my madden or married name? Thanks for your help!
